continued… Obj: draw Box-and-whisker plots representing a set of data Do now: use your calculator to find the mean for 85, 18, 87, 100, 27, 34, 93, 52, 91, 54, 59, 61, 82, 68, 78

Step 1 - Find the median. 18, 27, 34, 52, 54, 59, 61, 68, 78, 82, 85, 87, 91, 93, is the median of this data set. Step 2 – Find the lower quartile. *The lower quartile is the median of the data set to the left of 68. (18, 27, 34, 52, 54, 59, 61,) 68, 78, 82, 85, 87, 91, 93, is the lower quartile

Step 3 – Find the upper quartile. *The upper quartile is the median of the data set to the right of , 27, 34, 52, 54, 59, 61, 68, (78, 82, 85, 87, 91, 93, 100) 87 is the upper quartile Step 4 – Find the maximum and minimum 18, 27, 34, 52, 54, 59, 61, 68, 78, 82, 85, 87, 91, 93, is the minimum and 100 is the maximum.

In order to draw the box-and-whisker plot, Organize the 5 number summary  Min – 18  Lower Quartile – 52  Median – 68  Upper Quartile – 87  Max – 100

Notice, the Box includes the lower quartile, median, and upper quartile. The Whiskers extend from the Box to the max and min.

Ex 4: Use the following set of data to create the 5 number summary and a box-and-whisker plot. 3, 7, 11, 11, 15, 21, 23, 39, 41, 45, 50, 61, 87, 99, 220

Median 3, 7, 11, 11, 15, 21, 23, 39, 41, 45, 50, 61, 87, 99, 220 The median is 39

Lower Quartile ( 1 st Quartile ) (3, 7, 11, 11, 15, 21, 23), 39, 41, 45, 50, 61, 87, 99, 220 The lower quartile is 11

Upper Quartile ( 3rd Quartile ) 3, 7, 11, 11, 15, 21, 23, 39, (41, 45, 50, 61, 87, 99, 220) The upper quartile is 61

Maximum 3, 7, 11, 11, 15, 21, 23, 39, 41, 45, 50, 61, 87, 99, 220 The max is 220

Minimum 3, 7, 11, 11, 15, 21, 23, 39, 41, 45, 50, 61, 87, 99, 220 The min is 3

Min - 3 Lower Quartile - 11 Median - 39 Upper Quartile - 61 Max - 220
